Reduced Olfactory Memory Performance Is Associated with Executive Function Deficits in Older Adults.
Introduction: Previous research has identified an association between olfactory impairment (reduced odor sensitivity/ identification/ discrimination) and cognitive impairment in older adults. The present study focused on the relationship between olfactory memory performance and cognitive/affective functioning.
Method: Recognition performance for olfactory and visual stimuli (control condition) was tested through a matching task in older adults (n = 44; Mage = 76 years) and younger adults (n = 56; Mage = 24 years). Additionally, negative affect (anxiety, depression) and cognitive functioning were assessed via validated questionnaires and a neuropsychological test battery.
Results: The older participants performed worse than the younger adults in the olfactory memory task. In older adults, difficulties in remembering odors were associated with reduced odor identification and executive functioning (reduced cognitive flexibility). Affective well-being was not related to olfactory memory performance.
Implication: Olfactory memory impairment in older adulthood might be a marker for cognitive decline in areas related to executive functions.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
